Printing a novel compact triple-band monopole antenna on ceramic substrate

A novel miniaturized monopole antenna was designed on the 0.4mm-thickness Al₂O₃ ceramic substrate and a printed method that generated minimal environmental pollution was used to get the designed pattern. For the proposed triple-band antenna, the compact W-shaped electrode with different length in three arms was used as radiation pattern. Owing to the higher dielectric constant of Al₂O₃, the size of the triple-band antenna was minimized to 30 mm × 20 mm. The novel triple-band monopole antenna was proposed to operate at 2.4 (WLAN), 3.5 GHz (WiMAX), and 5.2 GHz (WLAN).
